Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed October 29, 1906. Serial No. 841,175-

To all whom it may concern:

Be it known that l, JonN'FnANK Ronnars, a citizen of the United States, residing at New Bediord, county of Bristol, State oi Massachusetts, have invented certain new and useful Improvements in Apparatus for Dyeing Yarn-Cops, of which the following is a specification.

My invention relates to apparatus for dyeing yarn in the conical cops, and it consists in certain elements and combination of elements fully specified and claimed hereinafter.

In order that those skilled in the art may understand, construct, and use my invention, I will proceed to describe it referring to the accompanying drawings forming part of this specification in which Figure 1. is a vertical central section of my invention. Fig. 2. is a cross section of Fig. 1 on line X X with the inclosing cover removed.

A is a cone shaped vessel; B is its base and O is its E is an opening in base B for discharge of spent dye fluid.

F is an inlet pipe leading from the dye pump, having of course suitable valve R. v

G is a discharge pipe also having a valve S.

His a conical cop of yarn placed in vessel A, and .I is a hollow perforated cone inserted in the hollow of conical cop H and takes the place of the paper cone upon which conical cop H has been wound.

K is a plug in the bottom of perforated cone J to close it at that point.

L are perforations in cone J.

M is a slight space outside of the outer circumference of conical cop II the'taper of vessel A being slightly different from that of conical cop H.

N is a chamber beneath cone H and O is a chamber above conical cop 1i.

P is a screw thread upon cover C to secure it to the vessel A which has a similar threaded portion to match it.

The operation of my invention is 'as follows: The valve in pipe F for inflow of dye fluid being opened and the discharge valve in pipe G being properly adjusted to provide for a flow through it which will give -and through discharge pipe G leaving the mordant of the dye evenly distributed in the yarn cop.

Many devices have been tried to cause an even resuit in dyeing yarn cops, but with little substantial success. By my apparatus hereinbefore described a perfectly even result is always obtained.

The originality of the idea comesin using the pe culiar taper shape of the yarn cop in conjunction with the reversed taper ofth iron flask to form a tight joint without the useof outside packing material as in other machines. The more pressure applied producing a corresponding tighter plug and obliging the dye liquor to penetrate the yarn itself with no openings or voids around the cop to waste the pressure and allow the dye liquor to pass outside the yarn cop, and this cop is also preserved in its cylindrical form without distortion or disarrangement of the wind. In practice, several or many flasks are connected up in series by suitable connecting pipes allowing a considerable quantity of yarn to be treated or dyed at one time.

Having now fully described my invention and the manner in which I have embodied it, what I claim as new and as my invention and desire to secure by Letters Patent is An apparatus for dyeing yarn cops, consisting of an inclosed conical vessel; regulated fluid supply inlet at its upper portion; a regulated discharge'at its bottom; the

vessel being of such form that a conical cop may be located in said conical vessel resting against its taper walls be neath the fluid supply opening and above the fluid dis charge opening; a chamber being formed between said conical cop and said discharge; a perforated inverted cone located within the central portion of said yarn cop and JOHN FRANK ROBERTS.
